Numerical modeling of breach process of landslide dams due to overtopping and its application
Yantu gongcheng xuebao, 2018 As a production of natural process, the landslide dam has poor structural stability, and most of which will finally fail due to overtopping, which will pose tremendous risks to the people and property in the inundated area.

Two new endemic species of Portulaca (Portulacaceae) from the Brazilian Pampa grasslands
Nordic Journal of Botany, EarlyView.Portulaca L. is a monophyletic, cosmopolitan genus of succulent plants comprising ca 153 species, with particularly high diversity in xerophytic ecosystems in tropical and subtropical regions. Based on morphological evidence, we describe and illustrate two new species from the Brazilian Pampa, Portulaca guaritensis and Portulaca guenoa.

A simplified physically-based breach model for a high concrete-faced rockfill dam: A case study
Water Science and Engineering, 2018 A simplified physically-based model was developed to simulate the breaching process of the Gouhou concrete-faced rockfill dam (CFRD), which is the only breach case of a high CFRD in the world.

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Effect of Different Core Slopes and Filters on Seepage for Horan Dam, Iraq
مجلة النهرين للعلوم الهندسيةA dam failure results in losses in terms of economy and infrastructure, in addition to the loss of many lives and assets. Inadequate seepage control procedures are typically the cause of seepage failure in earth-fill dams.

Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero
River Research and Applications, EarlyView.ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.
